2(2)+4(-1)=4+-4=0, so your answer is 0 hope this helps
Well you need to find the y-intercept (the number after the number with the x) and plot that number on the graph. next you need to find the slope (ex. 3x+4 the slope would be 3/1) and then you would plot the rest of the points using the slope. and last you would draw a line through the points.
Answer:
the answer is 2 + the square root of i forgot
Step-by-step explanation:
Take any 2 points from the given line and use the rule to find slope
(3,0) (0,-1)
Slope= y2-y1/x2-x1
Slope= -1-0/0-3= -1/-3 = 1/3
Final answer :
Slope = 1/3
So it’s the first option :)
